Hello,
(running current with OpenSSH_6.2, OpenSSL 1.0.1c 10 May 2012)
I'm trying to setup chrootdirectory in sshd_config as a test configuration
without success.
Here is a snip from my sshd_config
----
#(this is the default line)
Subsystem sftp /usr/libexec/sftp-server
#added the following match block
Match Group remote-sync, Address 127.0.0.1
ChrootDirectory /home/chroot/%u
ForceCommand internal-sftp -f LOCAL0 -l INFO
AllowAgentForwarding no
AllowTcpForwarding no
GatewayPorts no
X11Forwarding no
---
The home directory /home/chroot/sync is owned by root:wheel.
When I try to connect I get the following error:
cannot stat /usr/libexec/sftp-server: No such file or directory
What do I miss?
What is wrong with my test config?
Thanks for any input!!!
Didier
